The following code uses Stingray's RESTful API to retrieve the statistics for a pool. The code is written in PHP and uses STMRESTClient. This program does a single GET request for the statistics for the pool and then loops through response printing out each property and its value.
getpoolstats.php
<?php
# Display the statistics for a pool
require_once 'stmrestclient.inc';
$pool = "testpool";
print("<html><body>\n<br><b>Statistics for Pool $pool</b><br><br>\n");
print("<table>\n");
try {
$client = new STMRestClient();
$response = $client->get("pools/$pool", TYPE_STATS);
$stats = $response->statistics;
foreach ($stats as $field => $value) {
print("<tr><td>$field:</td><td>$value</td></tr>\n");
}
print("</table>\n");
} catch (STMConnectException $e) {
print ("Error connecting to the REST API: " . $e->getMessage());
} catch (STMAuthException $e) {
print ("Error logging into the REST API: " . $e->getMessage());
} catch (exception $e) {
print ('Error: ' . $e->getMessage());
}
print("</body></html>\n");
?>
Running the example
This code was tested with PHP 5.3.3 and uses the STMRestClient class that can be found here: Tech Tip: A Stingray Traffic Manager REST Client for PHP
